Many of my military peers may recognise that many things were part of a system of barter during our tours. For my Navy shipmates, we found cigarettes, Froot Loops and some items in “care” packages could be used to trade for watchstanding in certain ports of call. At other times, it might be a needed safety audit, such as that I could perform to use a boom box in a kitchen (galley). I was a ship certified electrical safety petty officer.
The Supply division received the stores. And strangely, Froot Loops were always missing from the single serving selection of breakfast cereal.
But onboard a cruise ship, these precious currencies are devalued. Just placed out in the cases at breakfast for everyone to enjoy.
